TEHRAN (FNA)- Archaeologists said they have discovered pieces of a stone inscription belonging to an ancient Achaemenid emperor in Persepolis in Iran’s Southern province of Fars.

The inscription was unearthed at the Palace of Xerxes King (Khashayar Shah) reigned around 520 BCE.

A team of experts is trying to attach the pieces together to decipher the text of inscription, said the team leader Professor Gian Pietro Basello of the University of Naples, Italy.

Basello is a specialist in historical philology of Iranian languages of the "L’Orientale."

He also claimed that he has found a few spelling mistakes in the inscriptions placed in the ruins of Persepolis.

“The texts of the inscriptions were written by people with a high level of literacy, but the mistakes happened when the engravers cut the texts into the stones," said Basello’s colleague, Adriano V. Rossi, during a seminar held in the Southern Iranian city of Shiraz.

A new review of the royal Achaemenid inscriptions discovered in Persepolis was presented at the seminar.

Established by Cyrus the Great, Achaemenid Empire was the first Persian Empire ruled in Western and Central Asia.

One of the Achaemenid kings, Darius I (518 BCE), built Persepolis as the capital of the Empire.

The importance and quality of the monumental ruins make it a unique archaeological site.
